Kaepernick working on his speed in the offseason

San Francisco 49ers quarterback Colin Kaepernick is using this offseason to improve on his speed, according to the Sacramento Bee's Matt Barrows.

Kaepernick, who became the first quarterback in FBS history to throw for more than 10,000 yards and rush for more than 4,000 during his four-year career at Nevada (2007-10), has been in Atlanta working with world-class sprinters.
